The slogan of the plugin says: "Simply turn any WordPress post, page or site into a fully functional wiki". Is it right? Because it's exactly what I'm looking for: the ability to add wiki features to a subset of pages, not to use a new post type with its own taxonomy and hierarchy. Furthermore, I'd like to let my themes display these features by design, not to inherit a display I cannot easily adjust.
Does the plugin do what I need or would it be a possibly huge enhancement?
